I have a compose navigation controller issue, as in I want to be able to mix composable , dialog and dialog<F: Fragment> destinations
so I construct my navController like

val context = LocalContext.current
val fragmentManager = LocalFragmentManager.current
val dialogFragmentNavigator = remember(
    context,
    fragmentManager
) { DialogFragmentNavigator(context, fragmentManager) }

val navController = rememberNavController(dialogFragmentNavigator)

but if I add a regular composable dialog destination to the graph, it will crash with

java.lang.ClassCastException: androidx.navigation.compose.DialogNavigator cannot be cast to androidx.navigation.fragment.DialogFragmentNavigator

[Carl Benson]

it seems like the navigator provider returns the wrong navigator? is it because they are registered with the same name?

[Carl Benson]

@Navigator.Name("dialog")
public class DialogFragmentNavigator(...)

[Carl Benson]

and

@Navigator.Name("dialog")
public class DialogNavigator : Navigator<Destination>() {

[Carl Benson]

it works fine if I don't have both dialog and dialog<F: Fragment> destinations

I do believe the names are somewhat important here and this seems like you just can't use both together out of the box. It's possible that maybe you could duplicate one of them with a new class name, and alter the annotation. it would be messy and cumbersome, but i don't see how else you could make them work together.

[Carl Benson]

yes, that is what I've come to realise too, I'll have to use my own navigator for one of the destinations

[Carl Benson]

I think the names are mostly used for the provider to find them, I'll file a issue and see if it gets picked up
